An adaptable, integrated, vernacular and low maintenance summer house was requested by the client. The demands of the housing program gave us the opportunity to use simple geometric shapes that responded to them in a successful way. The configuration of the cubes gave us the possibility of having individual spaces but also of having a complete unity by partly touching and overlapping into each other. The cubes create private, semi-public and public spaces in a complex way through a simple act. This house can serve for all possible constellations that can come up in a family life. The materials of the cubes present a game of contrasts between the transparent, reflective and opaque. The apertures respond to the surroundings opening towards the views of the lake and protecting against cold northern winds. All of that gives the building simplicity and at the same time a high complexity between its interior and the surroundings. Building with a material found on site rediscovers an ancient system which we often forget because of technological advances. Colors and textures in the walls merge with the landscape to bring house and environment together. A close relation with the client and a set of artists that designed some interiors and furniture gave a further step to the customization of the living requirements for the users.
